pro-tip: if you're into keyholders and findom, do NOT get into KMS, it's not AT ALL the same thing

cf. Opus 5.5: "The hyperscalers spend more on confidential computing than most EU clouds earn." 😭

finding that the answer to "what can you build today that relies exclusively on EU cloud services, inference, CDN, DNS, etc." is "quite a bit, but it's not gonna be comfortable"

Yeah that was immediately obvious from them offering Ultrafast on Bedrock, right?

he seemed distracted, stumbled on words a bunch

do you think ultrafast also compacts 8x faster

maaybe ultrafast is interesting? maybe. idk. so much fluff around it though. and ai-generated powerpoint to present to the coworkers you fired (replaced with dots) okay. whatever helps them IPO next year ig

cryptic post I know but just... lots of meh. really disappointed. "our biggest devday ever" okay sure.

I'm at OpenAI's DevDay event in San Francisco today - as I have for the past three DevDay events, I'm running a live blog where I'll be posting updates during the keynote, which starts in five minutes simonwillison.net/2026/Sep/29/...

OpenAI DevDay 2026 live blog

I’m at OpenAI DevDay today, in Fort Mason, San Francisco. Same as last year I’ll be live blogging the keynote and some other notes during the day. OpenAI gave me …

rust devs be: "use fluent query builders!" and then do: .filter("id", "=", 1)

Screenshot of a post by Tibo (@thsottiaux):

“I’ll explain the new Pro 200 plan differently, before I start live tweeting from DevDay on things that are going out!

Today we are going to ship a number of things that increase what you can do across the Plus and Pro plans. A lot of compute is online for this increase. As we increase the floor, we are changing the relative difference between plans to be

Plus = 1X
Pro 100 = 5X
Pro 200 = 10X

and we are reopening subscriptions for Pro 200 (we had paused it). If you have an existing plan you will keep the 20X multiplier for a bit and also receive a lot of additional credits because we know changes are hard even if it means that everyone will get more in the end.”

The phrase “for a bit and also receive a lot of additional credits” is highlighted in red.

the new Inside Out looks fire

openai announcement it has fluffy mascots I already fucking hate it

> underqualified to work as a cop ouch

Neat! Does this mark a change in your perception of those models or just a milestone in what you can achieve locally?

100

not yet! it got good recently.

but you get animated GIFs on your desktop for free!!?!?!?

bsky.app/profile/thso... looks like: still $200 but usage runs out twice as fast.

But idc about your personal assistant though I care about tokens... "we won't win with the best models" ok so we should look elsewhere then

shame though b/c mine is reaaaally good

thinking of letting others use my AI agent harness in exchange for AMERICAN DOLLARS but the problem in that otherwise foolproof plan is that anyone who's agent-pilled enough to look into obscure harnesses has already made theirs, most likely

Claude 5.5 Sonnet is live and it’s roughly Opus 5.5 but cheaper www.anthropic.com/claude-sonne...

A benchmark comparison table titled "Claude Sonnet 5.5" comparing four models: Sonnet 5.5, Sonnet 5, Opus 5.5, and GPT-6 Sol.
* Agentic coding (Terminal-Bench 4.0): Sonnet 5.5: 70.6%; Sonnet 5: 10.3%; Opus 5.5: 66.4%; GPT-6 Sol: N/A.
* Agentic coding (FrontierCode 1.1 Main): Sonnet 5.5: 46.2% (Max) / 52.1% (Xhigh); Sonnet 5: 42.4%; Opus 5.5: 54.4%; GPT-6 Sol: 49.3%.
* Agentic coding (CursorBench 4.0): Sonnet 5.5: 55.5%; Sonnet 5: 34.1%; Opus 5.5: 57.8%; GPT-6 Sol: N/A.
* Knowledge work (GDPval-AA v2.1): Sonnet 5.5: 1844; Sonnet 5: 1449; Opus 5.5: 1846; GPT-6 Sol: 1487.
* Knowledge work (AA-Briefcase v1.1): Sonnet 5.5: 1811; Sonnet 5: 1359; Opus 5.5: 1822; GPT-6 Sol: 1483.
* Multidisciplinary reasoning (Humanity's Last Exam with tools): Sonnet 5.5: 64.5%; Sonnet 5: 54.9%; Opus 5.5: 67.7%; GPT-6 Sol: N/A.
* Computer use (OSWorld 2.1 partial): Sonnet 5.5: 80.1%; Sonnet 5: 57.0%; Opus 5.5: 81.8%; GPT-6 Sol: N/A.
* Visual chart recognition (Chartography no tools): Sonnet 5.5: 61.6%; Sonnet 5: 15.6%; Opus 5.5: 64.4%; GPT-6 Sol: 53.6%.
Footnotes provide methodology notes regarding evaluation settings, Artificial Analysis pre-release testing details, and recent bug fixes affecting GPT-6 Sol benchmark scores.

A line graph titled "Agentic coding by effort level" on the CursorBench 4.0 benchmark, plotting Score (%) on the linear y-axis (20% to 60%) against Cost per task in USD on a logarithmic x-axis ($0.5 to $10+).
The chart compares four models:
* Sonnet 5.5 (blue line with labeled effort levels): Starts at "Low" (~$0.50, 36%), moving through "Med" ($0.70, 39%), "High" ($1.70, 48%), "Xhigh" ($3.80, 53%), and "Max" ($9.50, ~55.5%).
* Opus 5.5 (orange line): Tracks closely above Sonnet 5.5 at higher cost points, spanning from ~$1.20 per task (~44%) up to ~$12.50 per task (~58%).
* Sonnet 5 (grey line): Shows lower accuracy relative to cost, ranging from ~$0.90 per task (~25%) to ~$8.00 per task (~42%).
* GPT-5.6 Sol (light green line): Represents the lowest trajectory, ranging from ~$1.40 per task (~24%) to ~$7.00 per task (~34%).
Footnote: "CursorBench 4.0 does not report GPT-6 Sol performance publicly, so we report GPT-5.6 Sol here."
